    The Optimal Load Flow problem is a constrained optimization problem of large size and great complexity. For on-line implementation fast execution times and minimum computer storage are required. The proposed iterative scheme, reported in this paper, decomposes the Optimal Load Flow problem into real and reactive subproblems. At each iteration the two subproblems are solved using quadratic programm... View full abstract»

    This working group report presents the principal characteristics of a proposed definition of a file for the exchange of power system analytical data. The data covered by this proposed exchange mechanism is intended to update the existing "Common Format for the Exchange of Solved Load Flow Data" which has been in use since 1965. The principles outlined in this report will be implemented, after revi... View full abstract»

    The Transient Energy Function method is applied to assess the transient stability of a power network at the end of a complex disturbance sequence. Following this assessment, a method is devised for estimating the amount of generation-shedding required, early in the disturbance sequence, to prevent loss of synchronism. The technique developed for the above assessment is applied to a reduced model o... View full abstract»

    Five mini-papers summarize a panel session on single-pole switching at the 1985 Summer Power Meeting. Three of the reports describe single-pole switching applications in western North America. The fourth report surveys European applications of single-pole switching. The final report discusses protective relaying methods. The consensus is that single-pole switching can be a useful and feasible mean... View full abstract»

    This paper presents the details of a computationally efficient automatic voltage contingency selection algorithm developed for implementation at the AEP's new system control center in Columbus, Ohio. The methodology is based on the quantification of the real-time system-wide impacts of the transmission branch (line and transformer) outages on the load bus voltage profile via the fast computation o...

    Stabilization of power systems is investigated using a proportional-integral (PI) power system stabilizer. Digital (sampled-data) PI stabilizers as well as analog (continuous-time) PI stabilizers are examined in this paper. Two approaches, viz., the root-locus method and the suboptimal regulator method, are presented for determining the optimal stabilizer gains of the proposed PI stabilizer. The d...

    The key information required for quantitative evaluation of bulk power system reliability includes frequency and duration of multiple transmission line outages that cause system problems. Two fundamental approaches to reporting and analyzing transmission performance data to predict these multiple outages have evolved in the industry. These have been referred to as "unit" and the "component" approa... View full abstract»

    Operating a reliable and safe power transmission system is the goal of BPA. In doing so, BPA usually does not attain maximum transmission capacity due to continuous loading thermal limits placed on the transmission system. Thermal limit being the highest temperature at which a line conductor can be operated without violating minimum ground clearance criteria. However, lines do not instantaneously ...

    The Tokyo Electric Power Co., Inc. (TEPCO) and Mitsubishi Electric Corp. developed a large-scale dispatcher training simulator ELDIS (Electric Load DIspatching Simulator) in February 198 after three years of joint research. This simulator can be used not only for training in normal operating activities, but also for training in the handling of emergency and restorative operations under abnormal co...

    A method for suppressing Subsynchronous Resonance (SSR) in large turbine-generators, as a result of series capacitor compensation of power systems, is presented. This method utilizes a thyristor-controlled phase-shifter to modulate the generator active power by injecting a quadrature phase voltage in the system. The rotor speed deviation from the synchronous speed is used as the control signal. An... View full abstract»

    Weak transmission boundaries are shown to cause steady state and transient stability problems. The weak boundaries are defined by a loss of controllability property of the transient stability model. The loss of synchronism for fault contingencies can occur across these weak boundaries [7] if this boundary is weak compared to the other cutsets that encircle but are closer to the fault location.

    This paper presents the results of an experimental study involving the impact of voltage reduction on energy use and demand level on selected distribution feeders of differing load composition on the American Electric Power System (AEP). An eighteen month study was conducted on fifteen distribution circuits, during which voltage was reduced by a fixed five percent for the first twelve months, and ... View full abstract»
